Hi again,
short answer: You're doing it wrong!
While the "$number" format is widely used, it is impossible to use this here as the rule also needs to know where to get the data from (you can also use RegEx in source URL and other fields...).
So here are two things to check/fix:
1. Is the RegEx checkbox to the right of the "Package name" source enabled (exactly that is not visible in your screenshot)?
2. Instead of the "dollarNumber" format then use what we also described in our help articles:
https://support.jdownloader.org/Know...the-packagizer
and:
https://support.jdownloader.org/Know...ame-via-anchor
You probably don't want to type all of that by hand so:
--> Rightclick in the "then set...Packagename" field -> Danymic variables -> Package name wildcard [1-X]
